The iPhone Air’s real breakthrough is its battery

The iPhone Air’s thin design might be eye catching, and the amount of engineering that went into miniaturizing its logic board is impressive. But according to Gene Berdichevsky, co-founder and CEO of battery materials manufacturer Sila, the real breakthrough might lurk elsewhere inside the aluminum and glass enclosure. “The battery in the new iPhone is pretty remarkable,” Berdichevsky told TechCrunch. “The completely arbitrary, two-dimensional shape — you look at the shape, and it’s pretty amaz

Phone batteries are getting more compact, but the US is missing out

The Stepback arrives in our subscribers’ inboxes at 8AM ET. Opt in for The Stepback here. How it started Smartphone batteries are bigger than ever, while the phones themselves are shrinking. But whether you’re seeing the benefit — thin phones with big batteries — depends on where you live. The key is the introduction of sili

Does All Semiconductor Manufacturing Depend on Spruce Pine Quartz? (2024)

Here’s an idea you see spreading across the internet every so often: that all semiconductor and solar PV manufacturing depends on extremely pure quartz from the town of Spruce Pine, North Carolina. This quartz is used to make the crucibles which hold the molten silicon as it gets turned into silicon ingots, which are then cut into wafers and made into chips. The quartz needs to be very pure to prevent impurities from seeping into the silicon, and Spruce Pine is where this very pure quartz comes

Dutch battery startup LeydenJar’s silicon anode tech could pose a challenge to China

Battery materials startup LeydenJar has closed a €13 million ($15.2 million USD) round to scale up manufacturing of its silicon anode technology for an unnamed “leading U.S.-based consumer electronics company.” The Netherlands-based startup will use the funding, along with a €10 million commitment from the U.S. customer, to build the first phase of its facility, PlantOne in Eindhoven, Netherlands, which will open in 2027. Investors Exantia and Invest-NL lead the round. Today, a majority of the

The iPhone 17 Air Could Use a Silicon-Carbon Battery. What Is It?

Apple has taken the second approach with caveats. Rumors suggest the iPhone 17 Air's battery capacity will sit around 2,900 mAh, a steep drop from prior iPhone models, especially at the 6.6-inch screen size. But the company is supposedly making up for it with power-saving tricks to make sure battery life remains similar to other iPhones, including Apple's more efficient C1 modem that debuted on the iPhone 16e earlier this year. Luebbe declined to comment on whether Group14’s silicon-carbon comp

Meet the Silicon Valley Donors Backing California’s Redistricting Push

In the latest sign that Silicon Valley titans are increasingly throwing their weight behind political issues, Netflix co-founder Reed Hastings has contributed $2 million to support Gov. Gavin Newsom’s Proposition 50 campaign. The move is the latest underscoring how Silicon Valley’s deep-pocketed executives are increasingly wielding influence in California politics and beyond. The November ballot measure would scrap California’s independent redistricting commission, returning map-drawing author

Meta Defector Issues Devastating Psychological Takedown of Tech CEOs

Nick Clegg, a former Meta executive who left the company at the start of this year, has led many lives. Before jumping ship to the tech world, he was a deputy prime minister of the United Kingdom, a leader of the UK's Liberal Democrat party, and a member of Parliament — and still, the hubris and wealth he saw in Silicon Valley startled even the well-heeled British politico. In an interview with The Guardian pegged to the release of his new book, "How To Save The Internet," Clegg took aim at th

Group14 lands $463M from SK, Porsche, and others to make silicon anodes for EVs

Battery materials startup Group14 announced Wednesday it has closed a $463 million funding round to expand its manufacturing footprint, a sign that investors remain confident in the future of electric vehicles. The startup manufactures silicon anode materials, which significantly boost the storage capacity of lithium-ion batteries. Group14 currently operates three factories, two in the U.S. and one in South Korea. Despite headlines about softening demand growth for electric vehicles, the globa

The Militarization of Silicon Valley

But some tech executives and engineers are wrestling with the potential harms of the shift. Once they build autonomous drones and A.I. weapons for the military, they will have little control over how the technology is deployed. That has led to debates over whether more people will be killed by these advanced weapons than traditional ones, three engineers at Google and Meta said. “These Silicon Valley companies are hyper competitive, and in their drive to get into these defense sectors, there is

Apple now offers a separate Xcode 26 beta build for Apple silicon Macs

With today’s developer beta 5 releases, Apple also rolled out a new version of Xcode 26 beta that brings a notable change: two distinct download options, one of them being Apple silicon-specific. Yet another step beyond the Intel Macs era With today’s release of Xcode 26 beta 5 (build 17A5295f), developers can now choose between a “Universal” version, which runs on Apple silicon and Intel Macs, and one optimized specifically for Apple silicon Macs. According to Apple’s developer downloads pag

Low-Temp 2D Semiconductors: A Chipmaking Shift

Chipmaking giants like Intel, Samsung, and TSMC see a future where key parts of silicon transistors are replaced with semiconductors that are only a few atoms thick. Although they’ve reported progress toward that goal, that future is generally thought to be more than a decade away. Now, a startup spun out of MIT thinks it has cracked the code for making commercial-scale 2D semiconductors and expects chipmakers to have integrated them in advanced chips in half that time. CDimension has developed

The GOP's Message for Tech Billionaires: Be Like Peter Thiel

The unholy alliance between Silicon Valley and the Republican Party is no longer new. Between Elon Musk’s descent upon Washington, the number of Big Tech billionaires flying in to kiss President Donald Trump’s ring, and the expansion of the role of companies like Palantir in the US government, former president Joe Biden’s warning about the impending oligarchy has certainly borne out. All of this raises a question: Six months into Trump’s presidency, just how important are Silicon Valley billion

US probes imports on drones and a raw material used in chips and solar panels

The Department of Commerce has opened national security investigations into imports of drones and polysilicon , a raw material used in chips and solar panels. Among other things, officials are looking into "predatory trade practices" and the capacity of other countries to "weaponize their control over supplies" of drones, drone parts and polysilicon, as well as derivatives of each. The DoC commenced the investigations on July 1, but has only just disclosed them publicly. The probes could lead t

I don’t buy Samsung’s excuse for not using a silicon-carbon battery in the S25 Edge

Ryan Haines / Android Authority Samsung just launched the Galaxy S25 Edge, and it’s probably the most polarizing Galaxy phone in years. The new phone brings an impressively thin and light design along with a 6.7-inch display. It also has the S25 Ultra’s 200MP main camera. Unfortunately, this thin and light phone comes with several compromises, such as no telephoto camera and 25W wired charging power. However, the 3,900mAh battery is the Galaxy S25 Edge’s biggest cutback. Samsung could have use
